The work week is expected to get off to a complicated start Monday as freezing rain is predicted to confound commuters.
The National Weather Service at Pittsburgh, based in Moon, is warning that freezing rain will enter the region as early as tonight in some neighborhoods.
Today's mild temperatures will begin to give way in parts of Ohio and West Virginia starting at about 10 p.m. today, said meteorologist John Darnley. An advisory will be in effect through 10 a.m. Monday, predicting freezing rain that could deposit a tenth-inch of ice.
In Allegheny and the surrounding counties, a freezing rain advisory will be in effect from 1 a.m. to 1 p.m. Monday. "The snow will begin after midnight then will mix with sleet and freezing rain before changing to freezing rain. All this can leave accumulations of up to a half- to one-inch of snow with one-tenth-inch of ice," Mr. Darnley said. "It's going to impact tomorrow's commute."
Meantime, in the region's northern counties - Venango, Clarion, Forest and Jefferson - a warning will be in effect from 1 a.m. to 4 p.m. Monday. A quarter-inch of ice is expected to coat the ground.
While commutes may be tricky Monday morning, Mr. Darnley said the good news is that temperature will rise in the evening then hang around for a couple of days.
"We're looking for temperatures to max out at 44 degrees Monday then 57 on Tuesday and 54 on Wednesday," he said. The mercury will fall back to the 20s on Thursday and Friday.
